Hi Jan, Yes--your father is my cousin, though we haven't seen each other for a long time. If you want to contact me off list, you can write to: email@example.com
. Tell him hi (I remember you and your sister, though clearly I haven't seen you in a long time, either.)
I have just the names of the grandparents, James and Teresa (thus the name of your father and paternal grandfather). James was from Prague, I assume Teresa was, too, though I don't know that for a fact. I can't find her maiden name, though some asking around might turn it up.
Your father has another cousin, Leslie, who is in Utah and is interested in family genealogy. He may know more details about this. I'm not sure how to get in touch w/ him, though.
